I know quite a bit about this villain. He seems like an "ok" regular with 21/16/5 Stats and 53% cbet oop, 6% checkraise and 54% Check fold.

If hes checking underpairs i am not worried to get him off of them when i bet later streets and i dont want to be checkraise with this hand at all because it has such a high nut potential. Turn i think pretty much all options are viable. OTR im wondering if raising for value is ever a good idea here? I just dont believe he ever has a flush here when i block the As. I have probably never seen anybody check a flushdraw or a flushdraw with bottom pair. His betsizing obviously suggest that hes very very polarized and im blocking the value part of his range, so there is probably nothing he could call me with anyways.
